Application September 28, 1931, Serial No. 565,658 Renewed September 16, 1933 1 Claim.

The present invention relates to improvements in radiators for steam and hot water heating systems.

One of the important objects of the present in- 5 vention is to provide a sectional radiator wherein each section or unit comprises a pair of pressed or stamped out plates constructed of corrosion resisting material, said plates being disposed in intertting relation with the interfltting edge portions welded.

Another important object of the invention is to provide a radiator construction of the above mentioned character that includes a simple and efficient coupling between the adjacent sections or units.

A still further and important object is to provide a radiator construction of the above mentioned character wherein the parts are so arranged as to afford a free circulation of air around the coils as well as around the couplings connecting the adjacent sections together, thus offering a greater resistance to the separation of the joined parts, thereby preventing leakage.

A further object resides in the provision of a radiator of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purposes for which it is designed.

Other objects and advantages of the present 3o invention will become apparent when taken in connection with the accompanying drawing:

In the accompanying drawing forming a part of this specification, and in which like numerals designate corresponding parts throughout the several views:

Figure 1 is a side elevation of the sectional radiator embodying my invention;

Figure 2 is an end elevation thereof;

Figure 3 is an enlarged detail sectional view io illustrating the connection between the adjacent sections; and Y Figure 4. is a transverse section through one of the coils showing the interfitting relation between the plates.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates generally my improved radiator, the same comprising a plurality of sections or units, each of which is of the same construction and, therefore, the description of one section or unit will sufce for the description of all.

Each section or unit is formed of a non-corrosive material preferably Armco iron which is a very pure grade of wrought iron and which will resist corrosion better than steel. Other materials such as alloys of aluminum and chrome alloys which are of a corrosion resisting nature may also be employed. Each section is formed of two plates designated by the numerals 2 andl eo 3 respectively which are pressed to the desired shape whereby to form a plurality of spaced coils.

The plate 3 is slightly smaller than the complementary plate 2 so that these plates will have interiitting relation as shown very clearly in Figv ures 3 and 4 of the drawing. The plates are welded together as at 4, thereby providing a group of passages for the steam or hot Water that flows through the radiator connected with the heating system.

Before welding the complementary plates of each section together, the inner surfaces of these plates are coated with lampblack, the purpose thereof being to increase the absorptivity and therefore, the emissivity of the radiator.

The sections of the radiator are connected together through the medium of suitable couplings designated generally by the numeral 5, a pair of such couplings being associated with the upper and lower end portions of each pair of sec-1 30 tions or units as clearly disclosed in the drawing. The coupling includes opposed and aligned nipples 6 and 'l that are formed integrally with the opposed sides of the adjacent sections, it being understood of course, that the plates corn- 35 prising the sections are formed with openings around which these nipples extend.

The nipples are externally threaded as indicated at 9 for the reception of the connecting sleeve 8 which is internally threaded and this 90 construction is more clearly disclosed in Figure 3 of the drawing.

The endmost sections of the radiator may be provided with suitable supporting legs l0 and the radiator when -assembled is adapted to be connected with the heating system in the conventional manner.

The provision of a sectional radiator constructed in the manner disclosed and described., renders the same more efficient in its operation than the radiators now generally in use and furthermore, a radiator of the character embodied in the present invention can be manufactured Vat a much lower cost, both in time and labor than the ordinary radiator.

While I have shown the preferred embodiment of the invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted towithout departing jm)VV interiitting plates being welded together, a pair' of opposed nipples associated with the adjacent sections, said sections being formed With openings around which the nipples extend, and sleevelike couplings connecting the opposed nipples for aiording communication between the several sections.
